P.S. if I try to call the function straight out in the plugin (so it gets called everytime wordpress is loaded) I get this error:

“Call to undefined function wp_get_current_user() in /home/public_html/wp-includes/capabilities.php on line 1059”

However, I don’t get that error if I use the register_activation_hook – but again it doesn’t call the function for new accounts. That only calls the function for existing accounts and only if I deactivate and reactivate the plugin everytime.
